Description

Technical Field

[0001] This application relates to the field of metal powder processing technology, specifically to a 3D printing consumable collection device. Background Technology

[0002] In the field of metal additive manufacturing, after 3D printing technologies such as selective laser melting (SLM) and electron beam melting (EBM) complete the manufacturing of parts, a large amount of unmelted metal powder often remains on the surface and in the internal pores of the printed parts. The current industry standard post-processing procedure is as follows: the operator needs to remove the base plate carrying the printed part from the printer and transfer it to a dedicated residual powder recovery station, where the surface of the part is cleaned by manually holding a high-pressure pneumatic nozzle.

[0003] Manual operation is limited by the operator's physical strength and concentration, and cleaning a single part takes a long time (usually accounting for 30%-40% of the overall post-processing cycle). Especially when cleaning complex features such as deep holes, internal cavities, and mesh structures, it is necessary to repeatedly adjust the spray angle and position, which seriously restricts the production line cycle. For the large-scale production of multiple batches of miniaturized parts, operators need to perform high-precision repetitive operations for several consecutive hours. Complex features need to be manually cleaned area by area, which not only prolongs the working time of a single part, but may also cause powder accumulation due to blind spots, which may lead to cleaning blind spots or powder residue risks, affecting the quality of subsequent heat treatment or machining.

To this end, this utility model proposes: A 3D printing filament collection device, comprising: The box has a hollow interior, and the bottom wall of the box has a grid structure. A cleaning station is located above the grid structure inside the box. A clamping mechanism is installed in the housing in a height-adjustable manner, and the clamping mechanism is used to install the printing base plate and to drive the printing base plate to move up and down at the cleaning station. A top blower mechanism is disposed at the top of the housing and above the cleaning station, and the top blower mechanism is used to blow air from top to bottom; Four side blower mechanisms are respectively installed on the four side walls of the housing. Each side blower mechanism is equipped with multiple nozzles, and the multiple nozzles are tilted downward and / or horizontally facing the cleaning station.

[0016] Reference Figure 1-4 This application proposes an embodiment of the 3D printing consumable collection device, which includes: The box 10 is hollow inside, and the bottom wall of the box 10 is provided with a grid structure 20. A cleaning station is provided above the grid structure 20 inside the box 10. The clamping mechanism 30 is vertically mounted inside the housing 10, and the clamping mechanism 30 is used to mount the printing base plate 40 and to drive the printing base plate 40 to move up and down at the cleaning station. A top blower mechanism 50 is disposed at the top of the housing 10 and above the cleaning station. The top blower mechanism 50 is used to blow air from top to bottom. Four side blower mechanisms 60 are installed on the inner side wall of the housing 10. Each side blower mechanism 60 is provided with multiple nozzles 61, and the multiple nozzles 61 are tilted downward and / or horizontally toward the cleaning station. The hopper 70 is installed at the lower end of the box 10, with its upper end connected to the grid structure 20 and its lower end connected to the collection box 80.

[0017] When collecting metal powder from a 3D printed workpiece, a printing base plate 40 carrying the printed workpiece is mounted on a clamping mechanism 30. The clamping mechanism 30 moves to the cleaning station, and the top blowing mechanism 50 and the side blowing mechanisms 60 are activated to blow and clean the printed workpiece at the cleaning station. During the cleaning of the printed workpiece, the top blowing mechanism 50 and the four side blowing mechanisms 60 simultaneously blow air onto the surface of the printed workpiece from multiple angles. At the same time, the clamping mechanism 30 moves the workpiece up and down at the cleaning station, so that the blowing position of the nozzles 61 on the workpiece changes. This meets the need for blowing from different angles and positions to meet the requirements of complex features, covers cleaning blind spots, avoids powder residue caused by cleaning blind spots, improves powder cleaning and collection effect, and avoids the impact of powder accumulation on subsequent heat treatment and machining. In this embodiment, the lifting and lowering of the clamping mechanism 30 and the operation of the top blowing mechanism 50 and the four side blowing mechanisms 60 replace manual labor, reducing the intensity of manual labor. After the 3D printing material falls off the surface of the printed workpiece, it is collected from the mesh holes into the hopper 70, that is, the 3D printing material is collected into the collection box 80.

[0018] The top blower mechanism 50 can be a fan, a blower, or a nozzle. In this embodiment, refer to the attached drawing. Figure 3 As shown, the top blower mechanism 50 uses a nozzle.

[0019] In this embodiment, the housing 10 is provided with an openable and closable door, which is located below the nozzle 61, so that the operator can open the door and clamp the printing base plate 40 onto the clamping mechanism 30.

[0020] Specifically, the clamping mechanism 30 includes multiple telescopic members 31, which are vertically installed on the inner top wall of the housing 10. The clamping mechanism 30 also has multiple clamping members 32, which are respectively installed on the multiple telescopic members 31. The telescopic ends of the multiple telescopic members 31 are vertically distributed and used to drive the multiple clamping members 32 to move up and down, thereby allowing the printed workpiece to move up and down at the cleaning station. After the door is opened, the clamping mechanism 30 lowers to facilitate the installation of the printing base plate 40 by the operator. After the printing base plate 40 is installed, the clamping mechanism 30 rises back to the cleaning station.

[0021] Based on the above, as a preferred embodiment, four telescopic components 31 are provided, which are arranged in a rectangular shape. The four telescopic components 31 are respectively connected to the housing 10 through universal joints, and their telescopic ends are respectively connected to the clamping component 32 through universal bearings.

[0022] During the cleaning of the printed workpiece, the four telescopic members 31 can drive the corresponding clamping members 32 to rise and fall. Specifically, the four clamping members 32 can rise and fall synchronously or asynchronously. When the four clamping members 32 rise and fall synchronously, the printed workpiece moves up and down at the cleaning station. When the four clamping members 32 rise and fall asynchronously, the printed workpiece is flipped at the cleaning station, allowing the nozzles 61 to blow air onto the printed workpiece from different directions. When using the 3D printing consumable collection device described in this embodiment, the telescopic ends of the four telescopic members 31 can be controlled according to the shape and structure of the printed workpiece to fully blow air onto and clean the printed workpiece, reducing powder residue on the printed workpiece.

[0023] Furthermore, the clamping member 32 includes a clamping platform 321, which has a notch 322 that matches the corner of the printing base plate 40, and a threaded hole 323 at the notch 322. The four corners of the printing base plate 40 are respectively provided with internal threaded holes. When installing the printing base plate 40, the four corners of the printing base plate 40 are placed at the four notches 322 respectively, and the internal threaded holes are aligned with the threaded holes 323. The printing base plate 40 is then installed on the four clamping members 32 by fasteners.

[0024] Preferably, the bottom wall of the box 10 is provided with inclined guide plates on the four sides of the grid structure 20, and the guide plates are inclined downward on the side closer to the grid structure 20, so that the metal powder consumables in the box 10 can fall onto the grid structure 20 through the guide plates, and then fall into the hopper 70 through the grid structure 20.

[0025] Preferably, the mesh structure 20 has a plurality of mesh holes 21 extending through it from top to bottom, the diameter of the mesh holes 21 gradually decreasing from top to bottom, thereby improving powder throughput and anti-clogging ability.

[0026] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
